This student work is an example of medium performing. The student answered a majority of the mini lab questions, but did not seem to completely understand each mini lab. In mini lab 2, magnesium carbonate was used instead of zinc carbonate, and although the student was aware of this, still managed to discuss zinc in the answers. Some mini lab questions were not completed, like the second question for mini lab 4. This shows that the student doesn't completely understand double replacement reactions and how to determine which product is insoluble in an aqueous solution. The student did well in writing and balancing the chemical equations, which is why this student was not considered low performing. When it comes to the explanation, the student definitely did not read the instructions for writing it. Instead, the student gave a very short summary of the steps he/she took to finish this lab. There was no discussion or mention of how the products were determined, or how the reactions related to a specific type of chemical reaction. This shows that the student really didn't have a good grasp on all of the concepts involved in this assignment.
